Description
Technical Field
The invention relates to the technical field of building energy simulation, in particular to a method and a system for realizing an on-line simulation platform of an electric energy system of a building machine.
Background
The global statistics show that the building industry accounts for 30% of the total global final energy consumption and 27% of the total energy discharge. China is the largest building market in the world, the increasing completion area of China makes the stock of building areas in China continuously increased, and in 2018, china has about 98 hundred million tons of carbon emission and accounts for 28.8% of the world. Wherein the building operation, construction and infrastructure add up to about 23.5 hundred million tons of carbon dioxide, accounting for 24% of the total carbon emissions nationwide. In order to better reduce the energy consumption and carbon emission of the building, the improvement of the energy efficiency of the electric energy system of the building machine is the key point of work. In order to improve the energy efficiency of the electromechanical energy system, in the design stage, an analog simulation tool is needed to be used for estimating the energy efficiency, the energy consumption and the carbon emission of different schemes; in the operation stage, an analog simulation tool is required to be used for evaluating the energy efficiency, the energy consumption and the carbon emission of the system under different control strategies, and the energy efficiency, the energy consumption and the carbon emission are output to the control system to be used as decision basis.
However, simulation software of the building machine electric energy system can only be run locally by the existing simulation tool, the main stream tool is based on a foreign commercial software platform or developed secondarily on the basis of the foreign commercial software platform, on-line simulation cannot be realized, on-line deployment cannot be realized, and the simulation requirement of a real-time optimization control system required by the current engineering cannot be supported. The traditional simulation software only calls a local CPU to perform calculation, when the calculation problem is complex and the calculation time has higher requirements, the high-performance calculation power resources of the cloud can not be fully utilized, the multi-CPU/GPU parallel calculation can not be performed, the simulation software is easily limited by the local calculation resources, and the simulation time is difficult to shorten. The traditional method is to download special simulation tools to master high-level programming language and write C/C++/FORTRAN/Matlab/Python programs when customizing and constructing simulation models, and has the advantages of high requirements on users, large development difficulty, long test period, high simulation cost and large integration difficulty. Because the electric energy system of the building machine is complex, the mode implementation of the simulated system cannot be determined, the method has great flexibility and uncertainty, the mode of describing by adopting the relational database is not flexible enough for a long time, the data description mode is not directly related with the topology mode of the physical system, and the problems of high maintenance difficulty, more redundant data and inflexibility in modification are caused. When simulation is carried out, the solution of the complex virtual physical network corresponding to the electric energy system of the building machine lacks a high-adaptability and universal simulation solution kernel. The algorithm of the traditional calculation kernel based on partial differential equation numerical solution has high complexity, and a user cannot easily understand, develop and maintain; for the complex problems of nonlinearity and discontinuity, there is a problem of non-convergence of calculation, and a user is required to apply different calculation methods or simplify the problem.
